The neotropical orchid genus Telipogon Kunth was established in 1815 and currently comprises more than 250 species. Representatives of this genus are generally epiphytic plants lacking pseudobulbs. The stem is either abbreviated or elongate and the leaves are conduplicate. Flowers are usually resupinate with small sepals and petals similar to the lip, but sometimes different. The gynostemium is covered by stiff or soft hairs. This monograph is a presentation of taxonomic diversity of the orchid...

Diverse processes leading to doubled haploid (DH) plant production, such as microspore embryogenesis, gynogenesis, and distant hybridization followed by genome elimination, are based on the unique ability of plant cells to form haploid embryos without fertilization. All of these are possible because of various in vitro culture systems that enable the growth and development of tissues or single cells outside of the parental organism. The possibility of re-directing cell development from its...

At the Plant Breeding and Acclimatization Institute, National Research Institute (IHAR), research on plant tissue cultures began in 1970s. Some in vitro methods, such as anther cultures or isolated microspore cultures, have been directly used to produce homozygous lines in plant breeding. These methods are also a prerequisite for genetic manipulation for both scientific and practical purposes. Here, we describe the achievements of the Department of Biotechnology and Cytogenetics over the last...

To date, the use of liquid nitrogen (LN) in plant gene banks is relatively limited. Globally, in 2021, approximately 10,000 accessions were cryopreserved, and their explants were derived from in vitro plants. In Europe, out of 500 banks, only 20 use cryogenic temperatures to store plant germplasms. The implementation of seven conservation projects in Poland starting in the 1990s meant that the gene banking system in this country began to gradually develop. Plant gene bank is mainly based on the...

Interspecific hybridization is a significant plant evolutionary process and, concomitantly, a frequently used method to broaden the genetic variability of species and genetically improve crops. However, in distant crosses, many prezygotic and postzygotic barriers are encountered that prevent free, uncontrolled gene flow between species. Therefore, various experimental methods exploiting tissue culture, such as in vitro fertilization, embryo rescue, and protoplast fusion, have been developed to...

Somatic embryogenesis (SE) is a complex process that begins with regaining totipotency in some somatic cells, proceeds through embryo development and maturation, and ends with the formation of a whole plant. Since the first publications on SE in 1958, this regeneration process has been applied to the in vitro propagation of many plant species and has led to the development of some specific model systems.

This work focuses on the achievements of Polish researchers in the field of vegetative reproduction of plants under in vitro conditions. For more than 50 years, micropropagation methods have been used in Poland whenever vegetative reproduction is necessary. Most perennial horticultural crops, such as fruit plants, the majority of ornamental geophytes, and some vegetables (e.g., rhubarb and horseradish), require clonal reproduction owing to their high heterozygosity, i.e., their offsprings when...

Water stress is one of the major environmental constraints on wheat grain yield worldwide. One way to overcome this limitation is to evolve genetically stress-tolerant wheat genotypes that produce sustainable grain yields in water-scarce conditions. A field experiment was carried out to investigate the genetic diversity of 34 advanced wheat genotypes ( Triticum aestivum L.) and two commercial check varieties (Khirman and TD-1) for grain yield and yield-associated agronomic traits in moisture...

Laricifomes officinalis is a wood-decay fungus that is closely associated with old individuals of Larix decidua . In the twentieth century, L. officinalis was over-harvested because of its medicinal properties; consequently, it has become very rare or almost extinct in the Alps. In this study, we investigated the population of L. officinalis in the Alpe Veglia–Alpe Devero Natural Park (Val d’Ossola, Italy) to assess a preliminary conservation strategy. Population consistency was estimated...

Plant material obtained by pruning and production of deciduous fruit trees was evaluated as substrates for the production of the oyster mushroom, Pleurotus ostreatus . Lignified branches and stems from peach, apple, and pear trees were processed using a ripping machine to reduce the size of chips and to optimize disinfection. A completely randomized experimental design was proposed with six treatments (novel substrates) and one absolute control (100% hay substrate). Morphological variables such...

Recent ethnobotanical studies in the Caucasus, mainly in Georgia, reveal the significant ethnobotanical knowledge of local people related to wild edible plants. However, few studies have been conducted in the Lesser Caucasus, west Georgia, and Turkish Caucasus. This study aims to represent and evaluate the cultural importance of wild vegetable plants and their patterns of use along the Georgia–Turkey border. During the transhumance period in the summers of 2017 and 2018, 104 participants (65...

Fungi are among the most important organisms on earth, and they are essential components of terrestrial ecosystems. Their reproductive structures are strictly dependent and affected by environmental conditions, and community dynamics over time and space may be indirect indicators of the health status of forests. We combined macrofungal biodiversity indices in eight Mediterranean forests in Italy and surveyed 160 plots by standardized surveys, to evaluate the role of macrofungi as early...

The genus Hibiscus has more than 300 globally distributed species. This plant is well known for its bast fiber biogenesis, while its nutritional and medicinal values are largely ignored. Consequently, the nutritional properties of the Roselle variety, BJRI mesta-2, are unknown. Therefore, this study was carried out to analyze the nutritional composition of our selected Roselle tissues to support the nutritional requirements for humans in early summer in Bangladesh. Leaves were found to be a...

In this study, conducted at the Research Station of the Wrocław University of Environmental and Life Sciences, Poland, we sought to determine the communities of weed species and their temporal occurrence in a young apple orchard mulched with spent mushroom compost or Miscanthus straw applied to tree rows. A herbicide fallow treatment was used as a control. During the first year of application, both organic mulches protected against the germination of weed seeds stored within the soil. In...

Pinus sylvestris (Scots pine) and taxa from the P. mugo (mountain pine) complex hybridize in contact zones producing morphologically-intermediate fertile hybrids. However, the hybrid specimens sometimes express only the P. sylvestris phenotype. Such cryptic hybrids were detected among P. sylvestris and P. uliginosa in the western part of Błędne Skały in the Stołowe Mountains, where the pines grow on the tops of sandstone rocks and phenotypically resemble P. sylvestris , P. uliginosa , and...
